60-second interview with .... Sterling Perrin

Heavy Reading has published a report Photonic Integration, Super Channels & the March to Terabit Networks. In this 60-second interview, Sterling Perrin, senior analyst at the market research company, talks about the report's findings and the technology's importance for telecom and datacom.

"PICs will be an important part of an ensemble cast, but will not have the starring role. Some may dismiss PICs for this reason, but that would be a mistake – we still need them."

Cisco Systems' coherent power move

Cisco Systems’ acquisition of CoreOptics means the company has largely cornered the coherent market, says Telecom Pragmatics. 

Cisco Systems announced its intent to acquire the optical transmission specialist CoreOptics back in May. CoreOptics has digital signal processing expertise used to enhance high-speed long-haul dense wavelength division multiplexing (DWDM) optical transmission. Cisco’s acquisition values the German company at US $99m.

"Let me be clear, we don’t believe 100Gbps serial will dominate the market for a long time, or 40Gbps for that matter"

Still some way to go

Briefing: Dynamic optical networking 

Part 1: The vision .... back in 2000

I came across this article (below) on the intelligent all-optical network. I wrote it in 2000 while working at the EMAP magazine, Communications Week International, later to become Total Telecom.

What is striking is just how much of the vision of a dynamic photonic layer is still to be realised.  Back then it had also been discussed for over a decade. And bandwidth management, like in 2000, is still largely at the electrical layer.

And yet much progress has been made in networking technology. But the way the network has evolved means that a more flexible photonic layer, while wanted by operators, is only one aspect of the network optimisation they seek to reduce the cost of transporting bits.
